Mark Rober just set up one of the most interesting self-driving tests of 2025, and he did it by imitating Looney Tunes. The former NASA engineer and current YouTube mad scientist recreated the classic gag where Wile E. Coyote paints a tunnel onto a wall to fool the Road Runner.

Only this time, the test subject wasn’t a cartoon bird… it was a self-driving Tesla Model Y.

The result? A full-speed, 40 MPH impact straight into the wall. Watch the video and tell us what you think!

"But humans can do it with their eyes!" - says the man not selling a human brain to go with the optical sensors

I’m kinda confident that even RADAR + cameras was good enough, but they started shipping cars without it and even shutting off the RADAR in existing cars.

The main negative about LiDAR is the cost, but that’s quickly going down.

Why did they shut off radar?

The day I heard that was the day I realized he's a fucking idiot and I wanted nothing to do with his cars/tech.

Judging by how things have turned out...damn was that a good decision lmao

They pulled the RADAR from mine just before I took delivery, unbeknownst to me at the time. I received no sort of notification.

I saw the video pop up in my Youtube recommended, but didn't bother watching because I just assumed that any cars tested would be using LIDAR and thus would ignore the fake road just fine. I had no idea Tesla a) was still using basic cameras for this and b) actually had sophisticated enough "self driving" capabilities that this could be tested on them safely.

They tested a LiDAR rigged car, and it stopped just like you predicted. As of 2021, Tesla uses only cameras for FSD, and not even radar (which my stupid fine Toyota truck has).

They tested the idea safely by building the wall out of styrofoam, or at least that's what it looks like when it blows apart :)

Still think LIDAR is inferior to computer vision, Elon?

That was never in question, they just went with cameras because they're dirt cheap compared to lidar.

To be fair, I'd be surprised if half the humans driving didn't do the same.

Taking a guess here, but I think Mark Rober is not a big trump/musk fan? :D

I tried Waymo when I was visiting LA a few months ago. Genuinely terrific stuff.

I do not trust Teslas one bit though.

[–] kenoh@lemm.ee 12 points 1 day ago

Tesla doesn't use lidar for its sensing, living on the prayer that AI will just get good enough soon enough. Absolutely galaxy brained decision.

Tesla is trash.

Fuck Elon musk.
